摘要：
Disclosed is a method for manufacturing an electrochemical cell, wherein an insulation failure product can be accurately rejected, and an electrochemical cell can be used again after the insulation failure inspection. In the method for manufacturing the electrochemical cell (1), which is configured by hermetically housing an electrochemical cell main body (20) such that the leading end of a metal terminal (21) protrudes to the outside of the outer housing (10), an impulse voltage is applied between the metal terminal (21) and a metal foil layer (12), the waveform of the voltage applied to the capacitance between the metal terminal (21) and the metal foil layer (12) is measured, and the insulation failure inspection step is performed.
